1. which is the best paraphrase of the first paragraph?

the high school step team
karla's cousin jade urged her to join the step team."this afternoon you should defiantly try out! " jade suggested after the final bell rang.
"i know she wants the best for me," karla thought to herself," but i'm not sure i'd be any good, and i'd feel embarrassed if i messed up in front of others." karla had seen step teams in action: they stomped, they clapped, and they performed all kinds of synchronized moves
"our team is not as amazing as professional steppers, but we have a lot of fun! " jade said. "also, if you join the team, you will instantly have forty new friends! "
"i like the idea of forty new friends," karla thought to herself. "still, i'm worried about bringing up my math grade. i'd better play it safe for now" she decided.
"i really appreciate your concern, but i've got to say no for now" karla told jade. " i'm going for after school in math"
as karla turned away from jade and walked down the hall towards math class, she pictured her cousin shrugging her shoulders "okay do whatever you think is best," jade said. i'll see you at home"
karla went to the after school math session. the work was challenging and she had to concentrate, and she the teacher said nice things to karla about her efforts to grasp the ideas the were studying "and yet" karla thought" i still have a lot of work and study ahead of me" when the afterschool math session ended karla peeked into the gym.
"hey that's my cousin! " jade cried out. "come over here karla."
forty male and female students stopped in midroutine to look at karla. too embarrassed to refuse , she joined one of the lines
karla soon learned that stepping requires a lot of mental energy. "it's something like math" she thought silently, "but not exactly the same. i have to connect my brain to my body and make it move or stop at exactly the right moment. the key here is to execute every movement skillfully" very soon, karla had mastered the teams trademark "slap-finger-snap-slap-slap-stomp that night, karla got to work on math at first ,she felt guilty about the time she spent in gym.
then she reminded herself of the of saying."all work and no play make jack a dull boy." an english teacher once told her the origins of the cliché go all the way back to ancient egypt.
as karla worked she was surprised to find that she suddenly understood her algebra problems better than she had before. "there must be some carryover effect from step practice," she concluded. the concentration and focus that she exercised in step team practice seemed to her focus more clearly on her math. karla smiled as she thought," who would have guessed that spending time with step team might be more to my math grade than spending time on math work? "
later karla was as much as a member of the step team as anybody" i don't feel the least bit embarrassed anymore" she told jade "when i am stepping i feel completely focused on the rhythm of the team and working together with my forty new friends.
